  • 1. Guidance :- Mrs. A.A.BokareTopic :- EnErgy EfficiEnT AppliAncEs By: Abhilash A Dhatrak EE5E
  • 2. Energy efficient choices can save families about a third on their energy bill with similarsavings of greenhouse gas emissions, without sacrificing features, style or comfort.ENERGY STAR helps you make the energy efficient choice.If looking for new household products, look for ones that have earned the ENERGY STAR.They meet strict energy efficiency guidelines set by the Environmental ProtectionAgency EPA and US Department of Energy.If looking for a new home, look for one that has earned the ENERGY STAR.If looking to make larger improvements to your home, Environmental Protection Agency(EPA) offers tools and resources to help you plan and undertake projects to reduce yourenergy bills and improve home comfort.
  • 3. Energy Efficiency Purpose The purpose of energy efficient appliances and motors is to be able to supply the same level of energy service only using less energy. Efficient energy use is achieved primarily by means of a more efficient technology or process rather than by changes in individual behavior. Energy conservation reduces the energy consumption and energy demand per capita and thus offsets some of the growth in energy supply needed to keep up with population growth
  • 4. Making a Difference Along with saving money, energy efficient appliances and motors save the plant The energy used to run a product can be cut up to 80% There is a large potential to make a difference because all appliances energy usage can be cut  Fridges, washers, dryers, cars  Light bulbs, anything that plugs Into an outlet.
  • 5. Buy energy efficientIt may seem like theres little you can do to cut theamount of electricity you use – after all, few of uscould function without a fridge or washing machine,and that Sunday roast wont cook itself.But choosing more energy-efficient appliances cancut your electricity bills. Most white goods andcommon kitchen appliances have an energy-efficiency rating (A to G), through a schemeorganized by the European Union(EU). For coldappliances such as fridge-freezers look for A++ or A+ratings.
  • 6. Moving toward Energy-EfficientAppliancesEnergy Star is an international standard for energyefficient consumer products originated in the United States ofAmerica. It was first created as a United States governmentprogram during the early 1990s, but Australia, Canada, Japan,New Zealand, Taiwan and the European Union have alsoadopted the program. Devices carrying the Energy Star logo,such as computer products, kitchen appliances, buildings andother products, generally use 20%–30% less energy than requiredby federal standards. However, many European-targetedproducts are labeled using a different standard, TCOCertification, a combined energy usage and rating from theSwedish Confederation of Professional Employees (TCO) insteadof Energy Star
  • 7. If you are looking to buy new energy efficient appliances for your kitchen, there are acouple of ways to make sure that you are getting a good deal in terms of energysaving. All appliances are now rated using the EU Energy label so it is easy to spotenergy efficient appliances. In addition the Energy Saving Recommended logo fromthe Energy Saving Trust is applied to certain products.
  • 8. ElEcTronic BAllAsTEnergy Efficient Ballasts can be easily replaced with existing conventional choke, you will derive following benefits -Power Saving 30 - 50%.Increases tube life by about 70%.Ballast life is approx 50,000 hrs as against 10,000 hrs of conventional choke.Flicker free start and No blackening of walls.Works at input voltage as low as 70V and as high as 340V.Payback Period is less than Two Years.
  • 9. Power Line QualityTotal Harmonics distortion as low as 10%.Third Harmonics as low as 4%.Power Factor as high as 0.99.Two Years Warranty
  • 10. Compact Fluorescent LampA compact fluorescent lamp (CFL; alsocalled compact fluorescent light, energy-saving light, and compact fluorescenttube) is a Fluorescent Lamp designed to replace an incandescent lamp; some types fit into light fixtures formerly used for incandescent lamps.
  • 11. Compared to general-service incandescent lamps giving the same amount of visible light, CFLs use less power (typically one fifth) and have a longer rated life (six to ten times average). In most countries, a CFL has a higher purchase price than an incandescent lamp, but can save over five times its purchase price in electricity costs over the lamps lifetime. Like all fluorescent lamps, CFLs contain mercury, which complicates their disposal. In many countries, governments have established recycling schemes for CFLs and glass generally.
  • 12. LED Lighting LEDs (Light Emitting Diodes) are solid light bulbs which are extremely energy-efficient. When first developed, LEDs were limited to single-bulb use in applications such as instrument panels, electr- onics, pen lights and, more recently, strings of indoor and outdoor Christmas lights . Manufacturers have expanded the application of LEDs by "clustering" the small bulbs. The first clustered bulbs were used for battery powered items such as flashlights and headlamps. Today, LED bulbs are made using as many as 180 bulbs per cluster, and encased in diffuser lenses which spread the light in wider beams. Now available with standard bases which fit common household light fixtures, LEDs are the next generation in home lighting.
  • 13. Energy Efficient MotorEnergy efficient motors aremanufactured using the same frame asa standard T-frame motor, but thesehave : Higher quality and thinner steellaminations in the stator.More copper in the windings.Optimized air gap between the rotorand stator.Reduced fan loses.Closer matching tolerances.A greater length.
  • 14. Cast-resin Dry-type TransformersGEAFOL distribution and powertransformersin ratings from 100 to more than20 000 kVA and LI values up to170 kVare full substitutes for oil-immersed transformerswith comparable electrical andmechanical data.GEAFOL transformers aredesigned forindoor installation close to theirpoint ofuse at the center of the majorconsumers.
  • 15. Solar water heating Solar water heating (SWH) or solar hot water (SHW) systems compriseseveral innovations and many mature renewable energy technologies that have been well established for many years. SWH has been widely used in Greece, Turkey, Israel, Australia, Japan, Austria and China. In a "close-coupled" SWH systemthe storage tank is horizontally mounted immediately above the solar collectors on the roof.
  • 16. No pumping is required as the hot water naturally rises into the tankthrough thermosiphon flow. In a "pump-circulated" system the storage tankis ground or floor mounted and is below the level of the collectors; acirculating pump moves water or heat transfer fluid between the tank and thecollectors. SWH systems are designed to deliver hot water for most of the year. However,in winter there sometimes may not be sufficient solar heat gain to deliversufficient hot water. In this case a gas or electric booster is normally used toheat the water.
  • 17. Electronic Fan Regulator Electronic Fan Regulator that is extensivelyused to regulate and control the speed of the fans. Electronic fan regulator is an electronic device consisting of diacs, triacs, potentiome-tric resistance to provide stepless control of fan speed. This is an energy saving deviceand has advantages over the conventionaltype of fan regulators having more energylosses. These regulators can also be used as a speed regulator for manyother small F.H.P. motors used in mixer, laboratory solution mixer etc, withappropriate current ratings.
  • 18. Advantages of Energy-EfficientEquipmentMore than half the electricity used to power computer sis wasted. EPA estimates thata 1,000 computer office could typically save 200,000 kWh by enabling monitor powermanagement features – That’s about $20,000 a year or emissions from 27 cars.Turning computers off at night can double savings to 400,000 kWh.lEAdErshipWhen you specify ENERGY STAR equipment, you are following the lead of Stategovernment’s . Governor Pataki’s Executive Order 111 (Green and Clean State Buildingsand Vehicles) sets specific goals for saving energy and requires that State entitiespurchase ENERGY STAR equipment. Several progressive New York State jurisdictions,like Erie County, are adopting energy efficiency mandates. You can continue this trendand be recognized as a leader by your constituents.
  • 19. cosT sAvingsBy using ENERGY STAR office equipment, your utility bills will be significantly reducedand maintenance costs will be lower. For example, ENERGY STAR computers typicallyuse half the electricity ofstandard computers if they are enabled and turned off at night. And, there is oftenno purchase premiumwhen buying these products. ENERGY STAR products allow you to reallocate taxpayerdollars to meetthe needs that your constituents value most, for little or no capital investment.EnvironmEnTAl rEsponsiBiliTyBecause it uses less energy, ENERGY STAR equipment produces less greenhouse gasemissions, resulting in a cleaner, healthier environment. In addition, ENERGY STARproducts save natural resources (coal, oil and natural gas). The U.S. EPA estimatesthat the energy saved over the life of 50 high-volume ENERGY STAR copiers isequivalent to removing the annual emissions of 40 cars from the highway.
  • 20. EAsE of purchAsingMost New York counties already buy office products using New YorkState Office of General Services (NYOGS) contracts, which requireENERGY STAR compliance. NYOGS contracts satisfy New York State’scompetitive bidding requirements.
